Beit known that I, How; a citizen of the United States, residing at Waterbury, county; of New Haven',:- and-- State of Connecticut, have invented certain new and useful lmpr'ove'ments n'Fountam Syringe Bags, of which thefollowin'g'is a full, clear,'and exa-ct"descript ion-.

This invention relates "to' a syringe bag, more particularlyte an integral connector therefor for the outsideft elescopic' reception of anoutlet tube; i

make the bag with an -outlet extension within which was telescopicallyreceived one end of a hard rubber connector, over the other--- end of whichwas teles'cop'ed the end of the outletor noz'zle'supply tubef This method of i'malr'ing the are required in the separate manufacture-of the hard rubber connector' and the latter I must then be assembled with the finished 5 "ha-g;- A more serious objection is that the outlet end of the bag mu st {fit-very tightly around the connector-in order toprevent leakage orthe accidentalfwithdrawal. of the connector, hence infasseinb1ing-the finished" bag and connector when the outlet of the bag is mechanically stretched'in order to insert the connector, a certain percentage of the bags split at this point, entailing conbag outlet with the connector thematerial of the bag is constantly. under ayconslderable tension at thispoint, and as a resultthe 1 bags split or crack at the: outlet after a relatively short 'period of use, thereby entailing the loss of the bag when it is otherwise in good condition. Another defect of" the prior art construction is that as the hard rubber connector is relatively smooth and is provided with the ordinary forr'nof retaining shoulder. there is not sufficient frictional resistance to the withdrawal of the supply tube therefrom and the tube therefore is liable to slip off.

Another object ofmy '1 mowe -seamen BA'ce-f no I MCGEE,\

fountain invention is to pro vide' an improved; construction of fountain syringe-bag which willlengthen its lifeand tions of thebag.

LS-till-anoth'er object my invention is A furtherobject isi'toprovide aconnectorbetween a flexible fountain syringe bag and p 7 its outlet tu'b'e which is formed of-the bag Previously in the 1 manufacture of: foun-; tain syringe bagsit hasbeen'custom'ary to stock and'fintegralwith the bag," but which ible outlet tube 1 Y A still-furtherobjectis to-provide a Con TDGCCOD for the telescopicreception of a flex-v ible' tube," which will jallowgof the ready bag is relatively expensive,'as anumber of operations telescoping" of the tube 1 thereove'rfl-but which impart uniform wearino' qualities-to allporwill afl'ord. a strong frictional "resistance to thewithdrawal of-the tube. For a detailed disclosure of; the

,iFig. l isan elevation of'iny improved bag Referring to the drawings the numeral 1. represents a flexible rubber founta1n syringe x I invention] reference 1s had: to J theaccompanymg speci ficationand-'drawings, inwhichjlatter-a bag of any ordinary constr'uction, having an integral connector thereon designated generally by the numeral 2. This connector is formed by a cylindrical extension 30f the bag stock havinga reduced-and tapered portion 4 and an enlarged end-portion 5, the end l portion adjacent the tapered portion 4 hav-y- "ing a rearwardlyf inclined feather; edged shoulder 6. Within. the connector 2-andin tegrally united therewith is a sleeve 7.1of soft rubber stock, but the composition of which is such as to provide a'relatively stilfe'rmaterial than the bagstock. I 1

In making the bag any usual form of core is used but it is provided with anextension-" which forms the outlet bore'j8 of the finishedbag, and the mold is also provided with an An object of my invention is to provide a flexible receptacle of vulcanizable mate-- extension which in'connection with'the core extenslon forms the connector 2. The sleeve 7 of stiffer stock is first slipped over the core extension, and the molding and 'vulcanizing manner, the bag stock-flowing over. and integrally uniting with; the stock in the sleeve 7 during the operation.

To assemble the outlet or nozzle, supply tube with the finished bag all that is necessary is t force the end of the tube over the connector 2 in the usual manner, the reinforcement 7 stiffening the bag stock sufli ciently to permit this to be done without difliculty. As the soft rubber of the connector 2 is in direct contact with the inner wall of the soft rubber supply tube it offers a der and increasing the resistance to withdrawal. o

It will be seen that by my-invention a fountain syringe bag has been provided the material of which is not under excessive or unequal strain at any point thereby preventing crackingor breaking at the outlet and insuring a life for this portion of the 7 ing, comprising an interiorly reinforced" nipple offlexible vulcanized material taperbag equal to or greater in length than that of the remainder of the bag, the number of operations required to form the finishedbag. Y and connector has; been greatly reduced,

thereb 1 chea enin its manufacture and b forming the connector of soft rubber and,

providing it with the inclined feather edged shoulder the liability of accidental with-5 drawal of the supply tube from the connector has been greatly reduced;

While a specific application of the invention has been shown and described it is evident that it may be used Wherever it "is desired to form van. integralconnector for a flexible receptacle of svi'ilcaniz'able .material,
